Definitions

  • This invention relates to a sheet feed shaft used for a paper feed in a printing machine, a printer for an office machine and the like, and for a sheet feed such as a film in an overhead projector or the like.
  • a feed roller made of rubber has been widely used for a paper feed in a printer for an office machine. This tends to cause an unevenness in hardness of rubber, roundness, and concentricity with a shaft. Accordingly, in the case where multicolor printing is carried out by repeating the paper feed as in a color printing, a color deviation sometimes occurs due to the feed speed of paper and the deformation, and there occurs an inconvenience of unavoidably involving a change in quality and deformation caused by the wear of the feed roller.
  • the roundness of the metallic roller can be secured and there occurs no wear or deformation. This can be therefore used as a multicolor roller.
  • An aim of this invention is to provide a sheet feed shaft, which can, merely by plastic processing with respect to the peripheral surface of a metallic rod, feed paper or a sheet such as a hard film in an intended direction while maintaining an accurate position thereof.
  • a sheet feed shaft in which a plurality of spike-like projections which rise at an obtuse angle, at an acute angle or at right angles in a rotational direction of a metallic rod are formed by plastic processing on the circumferential surface of the metallic rod, said projections being provided in the entire axial direction or in plural areas of the metallic rod.
  • the apparatus for manufacturing a sheet feed shaft comprises a support bed for supporting a metallic rod, and a punch unit arranged opposite to the support bed to be reciprocated by a press, wherein a pair of perforating members having perforating edges formed on faces upposed to each other are mounted detachably on the punch unit.
  • a method for manufacturing a sheet feed shaft comprises: supporting a metallic rod on a support bed, and simultaneously applying a perforating processing to two portions in which peripheral surfaces of the metallic rod are opposed by a perforating member formed with perforating edges on faces opposed to each other to form a plurality of spike-like projections whose rising directions are contrary to each other.
  • FIG. 1 is a perspective view showing a principal part of a paper feed apparatus having a sheet feed shaft according to the present invention.
  • symbol S designates a sheet feed shaft formed from a metallic rod 1

  • the projections A and B adjacent to each other in the circumferential direction on the circumferential surface are reverse to each other in a rising direction.
  • the projection A as viewed from arrows P and Q in FIG. 2 will be a spike-like projection which rises long at right angles to or at an obtuse angle to the rotational direction of the metallic rod 1 as shown in FIGS. 6 and 7.
  • the proximal end of the projection A is hard to be bended, so that the length projected outward is short to provide a short projection A as shown in FIGS. 4 and 5.
  • the height of the projection A is selected to 20 to 150 ⁇ m. The same may be said of the projection B.
  • the sheet feed shaft constructed as described above positively catches both a relatively soft printing sheet as well as a relatively hard film used for an overhead projector even in all directions of the metallic rod 1 along with the sharply pointed projections A and B formed on the outer periphery of the metallic rod 1 to feed them in a set direction smoothly and to a set position properly by the cooperative operation with the feed roller 2.
  • the erecting height of the projections A and B can be set freely and accurately, which is materially high as compared with the conventional sand blast.
  • the projections A and B are not easily worn, and the positive feeding can be realized for a long period of years.
  • the multiple color printing with beautiful colors without deviation in color can be realized without occurring deformation in paper or films semipermanently.
